我们在乘坐高速行驶的列车时,都会有这样的感觉:周围静止的景物都在不断地与列车形成一种相对运动(移动),而且景物距观察者愈近,其相对移动的速度亦愈快,此时呈现在人们面前的景物轮廓因瞬间而过,越发显得模糊不清。 对于机动车驾驶人员来说,只有前方远处的目标相对移动缓慢,才有可能从容眺望,驾车自如。为了把问题说得明白,这里不妨引用一个物理工程学的概念——注视点,从理论上阐述一下注视点与安全行车的关系。 驾驶人员在驾驶车辆时,目视前方全神贯注,其两眼所能看到的
When we take high-speed trains, there is a feeling that the still scenery around us constantly moves (moves) relative to the train, and the closer the scenery is to the observer, the faster it moves relative to the train At this moment, the outline of the scene presented in front of people is blurry because of the moment. For motor vehicle drivers, only the distant front of the target relatively slow to move, it is possible to calmly look, driving freely. In order to put the problem to understand, here may wish to cite a concept of physical engineering - gaze point, elaborating the relationship between the fixation point and safe driving. When driving a vehicle, the driver visually focuses on the front and can see with both eyes
